2022-10-17dm: treewide: Use uclass_first_device_err when accessing one deviceMichal Suchanek
There is a number of users that use uclass_first_device to access the first and (assumed) only device in uclass. Some check the return value of uclass_first_device and also that a device was returned which is exactly what uclass_first_device_err does. Some are not checking that a device was returned and can potentially crash if no device exists in the uclass. Finally there is one that returns NULL on error either way. Convert all of these to use uclass_first_device_err instead, the return value will be removed from uclass_first_device in a later patch.

This construct is quite long-winded. In earlier days it made some sense since auto-allocation was a strange concept. But with driver model now used pretty universally, we can shorten this to 'auto'. This reduces verbosity and makes it easier to read. Coincidentally it also ensures that every declaration is on one line, thus making dtoc's job easier. Signed-off-by: Simon Glass <sjg@chromium.org>

2019-12-15dm: gpio: Allow control of GPIO uclass in SPLSimon Glass
At present if CONFIG_SPL_GPIO_SUPPORT is enabled then the GPIO uclass is included in SPL/TPL without any control for boards. Some boards may want to disable this to reduce code size where GPIOs are not needed in SPL or TPL. Add a new Kconfig option to permit this. Default it to 'y' so that existing boards work correctly. Change existing uses of CONFIG_DM_GPIO to CONFIG_IS_ENABLED(DM_GPIO) to preserve the current behaviour. Also update the 74x164 GPIO driver since it cannot build with SPL. This allows us to remove the hacks in config_uncmd_spl.h and Makefile.uncmd_spl (eventually those files should be removed).

2019-02-09mmc: omap_hsmmc: Workaround errata regarding SDR104/HS200 tuning failures (i929)Faiz Abbas
Errata i929 in certain OMAP5/DRA7XX/AM57XX silicon revisions (SPRZ426D - November 2014 - Revised February 2018 [1]) mentions unexpected tuning pattern errors. A small failure band may be present in the tuning range which may be missed by the current algorithm. Furthermore, the failure bands vary with temperature leading to different optimum tuning values for different temperatures. As suggested in the related Application Report (SPRACA9B - October 2017 - Revised July 2018 [2]), tuning should be done in two stages. In stage 1, assign the optimum ratio in the maximum pass window for the current temperature. In stage 2, if the chosen value is close to the small failure band, move away from it in the appropriate direction.

2018-11-14mmc: omap: Surround DM_FLAG_PRE_RELOC flag with OF_CONTROL checkBin Meng
When a driver declares DM_FLAG_PRE_RELOC flag, it wishes to be bound before relocation. However due to a bug in the DM core, the flag only takes effect when devices are statically declared via U_BOOT_DEVICE(). This bug has been fixed recently by commit "dm: core: Respect drivers with the DM_FLAG_PRE_RELOC flag in lists_bind_fdt()", but with the fix, it has a side effect that all existing drivers that declared DM_FLAG_PRE_RELOC flag will be bound before relocation now. This may expose potential boot failure on some boards due to insufficient memory during the pre-relocation stage. To mitigate this potential impact, the following changes are implemented: - Remove DM_FLAG_PRE_RELOC flag in the driver, if the driver only supports configuration from device tree (OF_CONTROL) - Keep DM_FLAG_PRE_RELOC flag in the driver only if the device is statically declared via U_BOOT_DEVICE() - Surround DM_FLAG_PRE_RELOC flag with OF_CONTROL check, for drivers that support both statically declared devices and configuration from device tree Signed-off-by: Bin Meng <bmeng.cn@gmail.com> Reviewed-by: Simon Glass <sjg@chromium.org>
